BOX AND COUPLING FOR CHAN PUMPS.

ApplicationA filed November 25, 19121., Serial No. 517,513.

To all whom t may concern: f

Y Be it known that l, EDWARD F. HAPPEN- sfioin, citizen ot' the United States of Amer-y ica, and resident of Cincinnati, inr the countyof Hamilton and State oi Ohio, have invented a new and useful lniproven'ient in a Box and Coupling for ChainvPunips, of

, which the -following is a specitication.

` of tubing.

It has been customary in chain pumps of the type disclosed in vthe accompanying drawing, to have ya section oi tubing whose upperv edge'was rolled into a bead which engaged and 'generally was soldered upon the bottom of the reservoir or receptacle, or" such chain pumps, and to have at the lower end of the short tubing E, a threaded cast coupling into which ther upper end of the upper section vof pipe B extending downwardly into the water supply, was screwthreaded. yAn objection to this constructionl is that there is; considerable play and sway inthe tube, due to the movement of the pipe and joint, and this would occasion the tub# ing becoming loose in the joint at the bottom of the reservoir. j v

Another objection to this was that it required the use of additional short sections An object ot my invention is to provide a rigid connection between the receptacle', the tubing, the coupling and the pipe.

Another object is to provide a coupling jointbetween the elements referred to, which joint will brace the tubing against the play and sway ot the pipe.

These and other objects are obtained by means described herein and disclosed in the accompanying drawing in which:

Fig. l is a sectional View of a chain pump having mounted on it a box and coupling embodying my invention.

Fig. 2 is a perspective view ot box and coupling` embodying my invention.

Fig. 3 is a (lange sectionview ot a box and coupling.

Fig. 4 is an enlarged sectional view of? line 4-4 of Fig. 3.

Fig, 5 is a detail view of a modified 'torni of coupling,

Fig. 6 is a fragmental, sectional view on an enlarged scale, showing in detail, parts of the device embodying my invention.

-My' invention lies in using a section oi tubing Ewhich is less than the length of the coupling D, rolling the upper end of the tubing intovthe vbead e at the bottom of the reservoir or box C, surrounding this tubing with the coupling having its upper end beveled and which upper end contracts with the plate C2, whereby the beading and the coupling are clamped upon the plate, thereby securing a compact joint and brac ing the saine against the play and sway of the pipe. n j

The chain pump A, has a customaryv link chain a, extending from the water supplyal to and about wheel a2 disposed in the pump box a3. As the chain a moves upwardly, from-` the water supply, it passes through the pipe B having disposedk atits vupper yend a receptacle C from which a flange c4. rEhe bore cl of lthe coupling is ol substantially the same size and shape as the slot c3. The coupling has a shoulder Z2 Jformed intermediate its ends. n rlhe lower end of vthe coupling yhas internal screw 'threads Z3 adapted to engage the threaded upper .end of the pipe B. A tubing section E is disposed within the coupling, and has its upper end rounded or turned upon itself to form a bead c Aadapted to lie upon the interior surface of the flange.r The lower end of the tubing is flared or turned upon itself so as to form a ring ev `which engages the shoulder on the coupling. ringy of solder c2 surrounds the bead e and engages the plate c2. A similar ring of solder es engages the ring c and the *coupling. A rib at is formed by overlapping the j v whereby the-spout c may communicate with..

the interior of the reservoir or receptacle.

Similar coupling means may be employed upon the lower end of the pipe B whereby the guiding member F1 is secured to said ipe.

The tubing section E `serves to rigidly sewasn longitudinal ends c5 and. c6 of the tubing,

cure the couplingin position euch thet the tapering upper end oit' the coupling` u' ly engages the flange on the plete. From this it is apparent that there will be practically no relative movement between the receptacle, the tubing', and, the coupling. lt is also epparent that should the tub i extend thru the perforation c"L somewhat loosely, the tapered end (Z of the coupling will extend into said perforation, possible to the extent of engaging the bead on the tubing, thereby clamping the bead on the tapered end of the couplin and the tapered face on the coupling bh ring' upon the Well ot the slot ln the modification shown in Fig. the coupling'li1 is provided at ite upper end with a cup like ila-ngo f, adapted to ecco1ninodate thelange ,1 'formed on the plate f2, :and into which flange 7" the upper end ot the tubing` f3 is locked as shown. A. suitable ring of solder f" Surrounds the joint between the plete and the tubing.

" l" cleiin l; ln e coupling device of' the class described the combination of a slotted plate, tubing` extending` through the slot in the plete, a. bead 'formed on the tribe adapted to engage one side of the plate, and a` coupling mounted on the tubing engaging the other side of the plate.

2. n :L couplingv device loit the class described the combination o'' ay Slotted plate, tx'xbing extenhlngthrough the slot in the plete, e bead formed. on the tubing engaging one side of the plete, compiling` mounted 0n the tubing.; und eng;tging the opposite side of the plate, and e shoulder on the coupling over which the one end. oi" the tubing is turned.

3. ln it coupling ydevice oit the class described the combination of e slotted plete, a coupling adapted to engageone side of the blatt mijacent to and substantially concentric with the Slot in the plete, and tubing extending' through the slot in the plete and haring one end thereof in engagement upon the plete :inf having* its other end in en- .Uient upon the interior ot' the coupling, the tubing; serving to rigidly connect the plete indk the coupling.

4l. In :i coupling device of the class described the combination of e slotted plate, a 'delige surrounding the slot in the plate, a tube extending; thru the slot, e bead on the tube h the flange, and a coupling ef.:- tenffling over the tubing' and secured thereto, the coupling and bead rigidly securing the flange between one another.

.ln teetin'iony whereof, l have hereunto :subscribed my neme this 18th day of November, 192i.
